MAP23: Unholy Temple (Doom 64)

MAP23: The Unholy Temple is the twenty-third map of Doom 64, designed by Tim Heydelaar. It uses the music track "Relentless Coil".

Walkthrough
The sky is dark with forever burning green fire, signifying how deep you are in Hell. You start off in a small moat that surrounds the central temple that vaguely resembles a pyramid. On top, you can barely see Hell knights and spectres viciously wanting to chase you down. In the moat, there are several arachnotrons that are luckily encountered one by one. There is a teleport at the end of the moat that takes you to the "second" floor of the temple. After defeating the spectres and Hell knights, you climb up the temple to turn on the switch which will you go inside the temple. Inside the temple are several corpses and two barons of Hell waiting to ambush you as soon as you step in. Continuing on there is a room with a couple of arachnotrons also waiting to ambush you as soon as you take the megaarmor.

Once you collect all three skull keys you need to enter a room to input a code-like sequence that corresponds to the colour of a key. The reason for this is because through-out the level, there are three locked doors that have the colour of the keys etched in right beside it. Depending on the order from left-to-right is what you must enter in the code room. If you get the code wrong, you are trapped and force to fight a Hell knight. If you get it right, the room will unlock and you must push a button that will remove one barrier from the exit, hence the reason why you must do this. Once you removed all barriers, you will be able to exit to the penultimate level No Escape.

Secrets

 * 1) After getting up the first floor of the temple, go to the other side till you face an Unmaker gun alongside energy cells on the outer walls. Turn around, get up the elevator and shoot the crest above the gun. The platform will drop for short time, so jump off the ledge to reach the secret.
 * 2) In the room where you enter the three colors codes, one side of the middle pillar without switch, is a hidden wall with a teleporter that will take you to the supercharge on the other side of the room.
 * 3) In the red door hall, go to the middle then face left, leaving the exit behind you. The wall at the very end can be lowered for rocket launcher ammo.

Routes and tricks
On the second tier of the temple, there are two sections of the walkway that trigger homing fireball traps from the buildings across the moat. These sections are marked by a pair of columns positioned near the edge of the walkway that support an even higher walkway which you traverse later on. Stop evenly in between the middle of the columns so the homing fireballs will hit them instead of you, then you can proceed safely.
